Design of single chip microcomputer control system of air conditioning fresh air unit

Abstract：In the information age today, air conditioning system as an important part of the intelligent building, and fresh air unit as part of the air conditioning system, how to achieve automatic control of the fresh air handling unit is particularly important, the fresh air handling unit automation control can effectively improve the running quality of central air conditioning system, improve indoor air quality, saving energy, improve management level.

This design uses STM32 microcontroller as the processor, mount TGS2611 methane sensor, DHT11 temperature and humidity sensor, temperature and humidity detection on the environment, the digital temperature and humidity signal sent to the microprocessor through a 2-wire serial interface, nonlinear compensation and temperature compensation of the relative humidity of the micro controller, nonlinear compensation and temperature compensation and relative humidity with a micro controller, TGS series of air quality detection device by the analog-to-digital converter through MCU control measurement, so as to realize the environmental temperature and humidity data, air quality data collection, according to the implementation of intelligent air conditioning machine to control these environmental data, and display the collected data.

Key Words: fresh air unit; STM32C8T6; temperature and humidity; TGS2611
